Title: Lets Learn Engraving!
Post by: CrescentSon on Nov 04, 2011, 00:42:48
Due to the amount of interest in my new hobby, I figured I'd start a thread that we could all participate in.

The plan is to start compiling resources, research, reference sources, tool designs, projects, tips, tricks, and a log of our progress. As many know, this is a brand new skill that I'm digging into, so I'm no expert. Hopefully, together we can progress faster than going it alone. So all you would be engravers, pick up an iron brush and dig in. If we have any experienced engravers, I think I can speak for everyone interested when I say please feel free to share.

With that in mind, here are a few resources. We can update this as we go To keep a master list so let me know what you guys are finding out there.

I'll start with what is already out there. Here are a few pics of my current work.

Currently I'm hand engraving using push gravers, and mostly in aluminum. I have dabbled with the engine covers on my CB750. My goal is to work my way up to engraving on firearms, knives, and engines.

I started with these:
(http://i300.photobucket.com/albums/nn34/drl001/CB750F3/P1040207.jpg)

My gravers were made out of HSS (high speed steel) drill shanks that I scrounged. Most of what I'm reading suggests that cobalt is the best metal, followed by HSS. High carbon steel is serviceable, but is considered old tech. I did however watch a vid on you tube where a guy used a concrete nail.

I also cut a couple of handles out of some scrap hardwood. I basically used these images to get my shapes down.

There isn't a lot of information out there for push engraving so I hit the power graving sites. Most recommend a 45* on both square and round gravers. For what I've been doing I've been using a lot sharper angles.

You may have noticed I have a couple of spokes in my graves. The metal ended up being a bit too soft, and only worked for more broad angled, heavier tools.

Welcome aboard GS. Will do sir.

Step 1: Making gravers.

As I said above my gravers are made from round stock. Most pros use either square stock, or square blanks with rounded shanks. Rounds are, ironically enough easily made from round stock. I had several worn out 3mm round HSS engraving drills, so that is what I used.

The first 4 types of gravers you'll need are flats, squares, onglettes, and rounds.

(http://www.trackofthewolf.com/imgPart/graver-tool_1.jpg)

Rounds are straight forward. I chucked up a drill on the drill press and cut it to length (I'm still experimenting with lengths). The next step was to grind a 45* angle with the belt sander. Pretty easy so far. a round is used to cut a rounded bottom trench, so that was really about it.

The next was the onglet. The ones I'm using are just about the same design as a round. The only difference is after cutting to length I spun it on the press and used a file to taper it to a 15* point. Think ice pick. The i threw it on the sander for a 45* bevel as well.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/P1040481.jpg)
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/P1040482.jpg)

Square gravers were a little harder to pull off with round stock. As the name implies it starts with square stock, so I had to grind the tips to a roughly square profile. then you grind a 45* angle diagonally making a diamond face with a pointed leading edge. I wanted finer cuts and line so my edges were brought in making a sharper leading point.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/P1040483.jpg)
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/P1040484.jpg)

Flats are basically chisels. Most produced for air-assisted engraving are quite thin, <1mm. Since I'm push graving, and wanting to learn traditional Japanese metal carving I mad mine the width if the stock so I could use it like a wood plane to smooth curves. One side was ground at a long sloping angle 20* or so, and a 35*-45* cutting heel was ground into the opposite side.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/P1040485.jpg)
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/P1040486.jpg)

To finish them off I threw a sheet of 400 grit wet/dry paper on a flat surface (granite cutting board) and honed all the faces. The cutting edges got run on 1000 grit for a quick polish.

That gives me a fairly good collection for basic push, or hammer and chisel engraving. I drilled a few holes in a scrap of maple for a quick holder. My next task is to come up with a vise.

The next hurdle is holding the material being engraved.

In the tiger tsuba videos the artist uses a traditional method of holding called a pitch bowl. As it sounds a pitch bowl is a hemisphere bowl, filled with pitch, and placed in a round base. The pitch is heated and the workpiece is hot glued in place. I'm considering actually trying to hot glue a coin down for my next project. You can get pitch bowls from most jeweler suppliers.

(http://shorinternational.com/images/Images25/25471.gif)
This kit can be bought for $60 - $70 usd here http://shorinternational.com/ChasingTool.php (http://shorinternational.com/ChasingTool.php)

Here is a cheaper alternative, with a write up here: http://www.ganoksin.com/borisat/nenam/jeweler-pitch.htm (http://www.ganoksin.com/borisat/nenam/jeweler-pitch.htm)

He also has a design out of cast concrete here: http://www.ganoksin.com/borisat/nenam/ballpage.htm (http://www.ganoksin.com/borisat/nenam/ballpage.htm)

Here is a metal pitch bowl made from a bearing race and a base cut off of a propane cylinder.
(http://i207.photobucket.com/albums/bb34/tcblades/engraving/97e2ec4d.jpg)

Here is the tsuba guy prepping the pitch bowl:
http://www.youtube.com/watch?v=Gkf9bDqn1fo&feature=youtu.be

The next technology for holding is the ball vise. It is basically a modern spin on the pitch bowl. It is a modular vise set on a steel ball base. They are pretty cost prohibitive starting at $300+. You can get these at most jeweler suppliers and engraving sites.
(http://i207.photobucket.com/albums/bb34/tcblades/engraving/ballvise.jpg)

The final technique is a simple drill press vise mounted to whatever base you have available. You can pick these up pretty cheap at Home Depot or any tool supply house.

Here is a version of that mounted on an old timers rotating table made from what appears to be a truck axle!

Here is my take on the concrete ball vise plan posted here.
http://www.ganoksin.com/borisat/nenam/ballpage.htm (http://www.ganoksin.com/borisat/nenam/ballpage.htm)

You'll need.
round vase or bowl
flat chunk of metal for a top
tools to cut and shape metal top
2-4 bolts (depending on size of mold)
piece of bar that will fit in the mold
concrete (I used fiberglass reenforced quickcrete)

I wanted more of a round shape than a steel bowl, and I wanted mine to be a bit smaller. I hit the stores and found the perfect bud vase/fish bowl for $1.97.

I needed a flat surface for either 'pitch' or to mount a vise. I scraped up a chunk of aluminum, and cut it to the shape of the top of the vase. Next I fit two bolts through the aluminum and down to a piece of flat bar for an anchor. I welded the bolts to the anchor to keep them from turning.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2804.jpg)

Test fit in the mold. Notice the bolts are head down with the nut above the work surface.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2805.jpg)

I filled the mold to the top, and dropped in the anchor with the work surface attached. I should have packed the concrete with something to get the bubbles out, but I didn't, and the finished product ended up with a lot of holes. Force in the anchor, and make sure the top is flush and the concrete is leveled off.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2806.jpg)

The weights were probably overkill. The next afternoon I tapped around the glass with a wrench and peeled away the pieces like shelling a hard boiled egg. The previously mentioned holes annoyed me so I sifted the rocks out of a cup of concrete and made a patch/skim coat. Let that dry, then folded up a fluffy towel for a base, and boom, insta-ball vise. All I need now is a piece of pipe for a base.

Very cool thread.
FYI: I have v.1 of the airgraver oscillating nicely, working out a method of varyng both stroke length and frequency independently without sacrificing 'power'. Still need to get a tungsten slug to make a proper hammer as stainless mushrooms pretty quickly due to higher psi requirements.

I noticed yesterday, that Harbor Freight had a selection of "needle files" that had all the cross sections you mentioned and more. They should be the right hardness, and just need the cutting angle ground in.
Plus you could still use them as files. 8)

Based on the above tutorial, I did some 'smithing.

I want to turn this into gravers and chisels.

Using this.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2826.jpg)

I'm not sure What kind of steel the circlip is, but one finished and treated it holds an edge well. I heated it in smallish sections with the torch, and beat it to shape on the 'anvil'.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2829.jpg)
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2827.jpg)

Here is the first one.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2833.jpg)

All sharpened, heated to cherry, quenched in oil, and polished on 2000 grit auto paper.

(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2853.jpg)

These all came from one old bastard file and one circlip. The files had to be 'forged' in a charcoal fire that i stoked to temp using the air compressor for bellows. All in all a simple project. Heat to cherry, let cool. Heat to cherry, hit with a hammer (repeat as necessary). Let cool and grind to shape, without overheating the tip. Heat 1/2 inch below the tip until the tip is the white straw color, and quench in oil or salt water.

TIP: I used oil because I'm engraving fairly soft metals, and could sacrifice a little harness to keep the tip from getting brittle. The tutorial used salt water, which cools faster, but some alloys will crack and such if cooled too fast. With pieces this small oil should quench fast enough to get a nice edge.

And here is the latest piece for our buddy JustinLonghorn (or Norsehorn depending on who you ask).

I lost this thread, I was looking for it in "members art". :-[
I backtracked through your build thread and found it again. The circlip should be made out of spring steel, that would make for an excellent cutting tool. I was a bit surprised at the re-heat treating, in the file to cutting tool page. I guess because I would just grind stuff to shape, instead of bending and filing. The hardness should be ideal as the file comes, but I could understand it if you needed to bend it to get the tool you need.
Different strokes. ;)

I spent almost twenty years working in a tool and die job shop, worked with a lot of alloys, O1, A2, D2, M2, S7, 4140, manganese etc. If you need any info, I would be happy to help.
Title: Re: Lets Learn Engraving!
Post by: CrescentSon on Nov 18, 2011, 00:24:18
I love the circlip chisels. By far my favorites, though the collection is growing. The reheating is new to me too, but seems to be the standard on all the engraving and carving forums. From a raw annealed steel sure, but it gets the job done well. It does make working the files easier.

In the meantime I'm working on the sculpting style via this tutorial.
http://www.engravingforum.com/showthread.php?t=3074

It started a a simple sketch, and then got fleshed in. Here is the basic concept.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2867.jpg)
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2875.jpg)

Couple of hours later:
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2877.jpg)
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2878.jpg)

I didn't give a whole lot of thought to layout since it is a learning piece, so I don't really know where it is going. Progress is slow since I stop to make new tools every few minutes. Really the only effective tools on this project have been assorted rounds, flats, and a few new scrapers.

The last few tools were made from old steel spokes. They forge well, and hold an edge really well after being hardened and tempered.

After the majority of the shaping was done I made a couple of rounded blunt points that were polished to near mirror. They were 'turned' in the drill press, and shaped with an angle grinder. The next step was to polish from rough grit down to 2000 grit wet/dry.

The majority of the tooling marks were removed by 'burnishing' the curved surfaces. You take the polished blunt
and rub the surface of the work, alternating directions and going lighter on each pass to brighten the surface. The process is similar to polishing a surface with progressively finer sandpaper.

I really didn't have a process since this was the first attempt, but now that I have a path to follow I'll photograph and document the next half step by step. If you guys have any specific questions, ask now and I'll try to address them as I go.

Title: Re: Lets Learn Engraving!
Post by: CrescentSon on Nov 20, 2011, 01:42:04
Ok, starting on the opposite side now. The outlines lines were scratched in pretty light so I had to open them up and get the recessed bamboo to the approximate depth. I started with a simple flat chisel at a steep sideways angle and gouged out a deep line to keep the tool in place as the bamboo gets dug out. The flat side down is good for heavy removal, and if you flip it over it serves as a decent micro plane.

(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/1119112.jpg)

During the trenching the shapes were kept simple. The good news is the material comes off pretty quick especially when using a chasing hammer. For he time being my hammer is just a 2" x 3", 1/2" thick piece of scrap steel. It is actually pretty handy. The characteristics of the chisel movement can be adjusted depending on which face of the block I use to strike with. Once the lines are roughed in I took shallower passes and used less sideways angle to round the cylinder shape. After that I drove the chisel straight in to create the lines for the bamboo.

(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/1119111.jpg)

The next steps were a little more complex. I switched to rounds and scrapers to shape the indentions between the nodes. It is a pretty tedious process of angling, gouging, and scraping that I couldn't begin to put into words.

(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/1119113.jpg)

These did the bulk of the work.

(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/1119114.jpg)

It was damn hard to get into the small spaces closer to the sword, so there was a lot of scratching withthe smallest rounds to remove the material.

After the shaping was nearing completion I went to work almost exclusively with rounds to lay in some detail, and hatch style shading. Still a long way to go, but I'm starting to see some composition. The next step is to sketch in the bamboo leaf motif in the blank area (if I can finally settle on it...).
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/111911.jpg)



And 76/356, thanks for the kind words. This really isn't that hard once you tool up, but yes it does take a lot of patience to sit for hours chiseling a piece of scrap aluminum. If you tried it, I promise you'd be hooked though. I just turned on some Tom Waits and dug in. Very meditative.

Title: More Tooling Up
Post by: CrescentSon on Dec 07, 2011, 01:47:19
Sorry for the lack of recent updates, as the hoidays roll on I get busier and busier. I have done quite a bit more tooling up.
 
Most of the pieces in this picture, though handy, are not needed to do standard bright cut style engraving. Since I'm experiminting with deep sculpute engraving I end up making pretty much every style tool I can find an image or description of.
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2917.jpg)
 
The handiest tools yet, are the most utilitarian and basic. I drilled a 3mm hole in a scrap of pine dowel for a graver handle, and I took the torch to the end ov a piece of PVC pipe and made a base for the concrete ball vise. I also made a small chasing hammer out of a 3" piece of rebar. I still need to snap a pic of that one.

(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2913.jpg)
 
I'll post some progress on the piece in a bit. I work on it at least a few minutes everyday, but it has been progressing fairly steadily.

This shot is well over a week old, but I'll get some new stuff up tomorrow. I'm getting a lot more confident with the shading lines, and cross hatching. That is mostly due to this technique I picked up from followingtheironbrush.org.
 
(http://i300.photobucket.com/albums/nn34/drl001/FORUMS/100_2908.jpg)
 
Using a small diameter wire chisel (made from a bed spring) as a fulcrum, you can control the depth and derection of a fine line. Once I practiced a bit, I got to the point that I could roll the fulcrum to get longer lines without picking up the chisel point.
 
I really cant wait to get this piece done so I can work on some bright cutting. This deep sculpting just doesn't have the realitively instant gratification of a more 2d approach.

Thanks Lee, I meant to mention the evils of overheating PVC. Its all good on the graver too. I'm having plenty of fun with the hammer and chisel while I'm learning the basics.

Here is where it sits today:

It is kind of hard to see it, but it will be some bamboo leaves mixed in with 'wave' thingies. I'm still unsure of the overall design, and the fate of that last blank section. We'll have to find out together later. I worked nights last night, and only had a couple hour nap today. I'm off to bed gents.

I know its not even close to the same thing, but do you have any info on acid etching?  For the clutch cover on my XJ build, I'm thinking of laying down a resist layer (plasti-dip) and burning away the image (used for my avatar, but much higher res) with a cnc laser cutter, then acid etching, painting, and pealing away the resist.  Most of the info I've found is relevant to use on electronics control panels, not cast engine parts, and nothing covers laser cutting the mask, so will be doing experimental pieces first, of course.

Cheating, I know.  Got loads of respect for the real stuff, have always loved how it looks (ever since seeing medieval armor in museums as a kid).  But when the world gives yah laser cutters, you make laser cut filagree (on flat surfaces).  Figured you might have come across something more directly applicable in researching the traditional techniques.
